Department of Medical Oncology Faculty Papers

The availability of blood-based diagnostic testing using a non-invasive technique holds promise for real-time monitoring of disease progression and treatment selection. Circulating tumor cells (CTCs) have been used as a prognostic biomarker for the metastatic breast cancer (MBC). The molecular characterization of CTCs is fundamental to the phenotypic identification of malignant cells and description of the relevant genetic alterations that may change according to disease progression and therapy resistance. However, the molecular characterization of CTCs remains a challenge because of the rarity and heterogeneity of CTCs and technological difficulties in the enrichment, isolation and molecular characterization of CTCs. In this …

Kinase-Independent Function Of Rip1, Critical For Mature T-Cell Survival And Proliferation., John Bertin, Peter J. Gough, Jianke Zhang, John P. Dowling, Yubo Cai

Department of Microbiology and Immunology Faculty Papers

The death receptor, Fas, triggers apoptotic death and is essential for maintaining homeostasis in the peripheral lymphoid organs. RIP1 was originally cloned when searching for Fas-binding proteins and was later shown to associate also with the signaling complex of TNFR1. Although Fas exclusively induces apoptosis, TNFR1 primarily activates the pro-survival/pro-inflammatory NF-κB pathway. Mutations in Fas lead to lymphoproliferative (lpr) diseases, and deletion of TNFR1 results in defective innate immune responses. However, the function of RIP1 in the adult lymphoid system has not been well understood, primarily owing to perinatal lethality in mice lacking the entire RIP1 protein in germ cells. …

Mirna-145 Increases Therapeutic Sensibility To Gemcitabine Treatment Of Pancreatic Adenocarcinoma Cells., Yong Lin, Xin Ge, Yiyang Wen, Zhu-Mei Shi, Qiu-Dan Chen, Min Wang, Ling-Zhi Liu, Bing-Hua Jiang, Yuan Lu

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Pancreatic adenocarcinoma is one of the most leading causes of cancer-related deaths worldwide. Although recent advances provide various treatment options, pancreatic adenocarcinoma has poor prognosis due to its late diagnosis and ineffective therapeutic multimodality. Gemcitabine is the effective first-line drug in pancreatic adenocarcinoma treatment. However, gemcitabine chemoresistance of pancreatic adenocarcinoma cells has been a major obstacle for limiting its treatment effect. Our study found that p70S6K1 plays an important role in gemcitabine chemoresistence. MiR-145 is a tumor suppressor which directly targets p70S6K1 for inhibiting its expression in pancreatic adenocarcinoma, providing new therapeutic scheme. Our findings revealed a new mechanism underlying …

Are Researchers Registering Systematic Reviews In Clinicaltrials.Gov?, Gary E. Kaplan, Ms, Ahip

Academic Commons and Scott Memorial Library Staff Papers and Presentations

BACKGROUND:

ClinicalTrials.gov (CT) is an increasingly important resource for systematic reviewers attempting to identify published and unpublished clinical studies. In addition to clinical studies, however, some searches of the CT database also return systematic reviews (SRs). When I inquired about the SRs appearing in the results, the NLM Help Desk responded that “We do not recommend that systematic reviews be entered in ClinicalTrials.gov, since we only want the results of a clinical trial entered once. However, we will not refuse them if they are entered.” I wanted to find out how many SRs are included, describe their characteristics, and suggest …

Impact Of Hur Inhibition By The Small Molecule Ms-444 On Colorectal Cancer Cell Tumorigenesis., Fernando F. Blanco, Ranjan Preet, Andrea Aguado, Vikalp Vishwakarma, Laura E. Stevens, Alok Vyas, Subhash Padhye, Liang Xu, Scott J. Weir, Shrikant Anant, Nicole Meisner-Kober, Jonathan R. Brody, Dan A. Dixon

Department of Surgery Faculty Papers

Colorectal cancer (CRC) is the third most common cancer and a leading cause of cancer-related mortality. Observed during CRC tumorigenesis is loss of post-transcriptional regulation of tumor-promoting genes such as COX-2, TNFα and VEGF. Overexpression of the RNA-binding protein HuR (ELAVL1) occurs during colon tumorigenesis and is abnormally present within the cytoplasm, where it post-transcriptionally regulates genes through its interaction with 3'UTR AU-rich elements (AREs). Here, we examine the therapeutic potential of targeting HuR using MS-444, a small molecule HuR inhibitor. Treatment of CRC cells with MS-444 resulted in growth inhibition and increased apoptotic gene expression, while similar treatment doses …

Promoting Health And Quality Of Life Along The Care Continuum: Creating A Nursing Curriculum For Today’S Health Care Environment, Kathleen D. Black, Mary Bouchaud, Denise Brown

College of Nursing Posters

Background

The focus on traditional acute, hospital-based health care is being replaced with a new paradigm aimed at providing primary care, care of populations, and care across transitions and providers. The Institute of Medicine’s report (2010), the “Future of Nursing” emphasized the need for nurses to lead health care change and called for nursing education focused on a community and population-based perspective, person centered care, and emerging roles for nurses across the care continuum. In response, the Jefferson College of Nursing embarked on the ambitious task of designing a new and innovative baccalaureate nursing curriculum over a 13 month period.

Mlkl And Fadd Are Critical For Suppressing Progressive Lymphoproliferative Disease And Activating The Nlrp3 Inflammasome., Xixi Zhang, Cunxian Fan, Haiwei Zhang, Qun Zhao, Yongbo Liu, Chengxian Xu, Qun Xie, Xiaoxia Wu, Xianjun Yu, Jianke Zhang, Haibing Zhang

Department of Microbiology and Immunology Faculty Papers

MLKL, a key component downstream of RIPK3, is suggested to be a terminal executor of necroptosis. Genetic studies have revealed that Ripk3 ablation rescues embryonic lethality in Fadd- or Caspase-8-deficient mice. Given that RIPK3 has also been implicated in non-necroptotic pathways including apoptosis and inflammatory signaling, it remains unclear whether the lethality in Fadd(-/-) mice is indeed caused by necropotosis. Here, we show that genetic deletion of Mlkl rescues the developmental defect in Fadd-deficient mice and that Fadd(-/-)Mlkl(-/-) mice are viable and fertile. Mlkl(-/-)Fadd(-/-) mice display significantly accelerated lymphoproliferative disease characterized by lymphadenopathy and splenomegaly when compared to Ripk3(-/-)Fadd(-/-) mice. …

Four-Dimensional (4d) Subharmonic Aided Pressure Estimation For Monitoring Neoadjuvant Chemotherapy Response Of Breast Cancer, Kibo Nam, Maria Stanczak, Anush Sridharan, Adam C. Berger, Tiffany Avery, John R. Eisenbrey, Flemming Forsberg

Department of Radiology Posters

Introduction

Neoadjuvant chemotherapy is a well-established treatment option for patients with non-metastatic breast cancer. The patient response is correlated with survival. However, the optimal method for monitoring neoadjuvant therapy response has not been established. One factor that may affect the response of neoadjuvant therapy is the interstitial fluid pressure (IFP). Increased IFP prevents an effective delivery of therapeutic agents and reduces the efficacy of the therapy. Recently, subharmonic-aided pressure estimation (SHAPE) using contrast-enhanced ultrasound (CEUS) has been developed and its potential was demonstrated in animals as a non-invasive technique for IFP measurements. The SHAPE method estimates IFP based on the …

Tau Phosphorylation At Alzheimer's Disease-Related Ser356 Contributes To Tau Stabilization When Par-1/Mark Activity Is Elevated., Kanae Ando, Mikiko Oka, Yosuke Ohtake, Motoki Hayashishita, Sawako Shimizu, Shin-Ichi Hisanaga, Koichi M. Iijima

Department of Neuroscience Faculty Papers

Abnormal phosphorylation of the microtubule-associated protein tau is observed in many neurodegenerative diseases, including Alzheimer's disease (AD). AD-related phosphorylation of two tau residues, Ser262 and Ser356, by PAR-1/MARK stabilizes tau in the initial phase of mismetabolism, leading to subsequent phosphorylation events, accumulation, and toxicity. However, the relative contribution of phosphorylation at each of these sites to tau stabilization has not yet been elucidated. In a Drosophila model of human tau toxicity, we found that tau was phosphorylated at Ser262, but not at Ser356, and that blocking Ser262 phosphorylation decreased total tau levels. By contrast, when PAR-1 was co-overexpressed with tau, …

Division of Gastroenterology and Hepatology Faculty Papers

A comprehensive -omic, computational, and physiological approach was employed to examine the (previously unexplored) role of microRNAs (miRNAs) as regulators of IAS smooth muscle contractile phenotype and basal tone. MicroRNA profiling, genome wide expression, validation and network analyses were employed to assess changes in mRNA and miRNA expression in IAS smooth muscles from young vs. aging rats. Multiple miRNAs, including rno-miR-1, rno-miR-340-5p, rno-miR-185, rno-miR-199a-3p, rno-miR-200c, rno-miR-200b, rno-miR-31, rno-miR-133a and rno-miR-206 were found to be up-regulated in aging IAS. qRT-PCR confirmed the up-regulated expression of these miRNAs and down regulation of multiple, predicted targets (Eln, Col3a1, Col1a1, Zeb2, Myocd, SRF, Smad1, …

Cmv-Specific Cd8 T Cell Differentiation And Localization: Implications For Adoptive Therapies., Corinne J Smith, Michael Quinn, Christopher M Snyder

Department of Microbiology and Immunology Faculty Papers

Human cytomegalovirus (HCMV) is a ubiquitous virus that causes chronic infection and, thus, is one of the most common infectious complications of immune suppression. Adoptive transfer of HCMV-specific T cells has emerged as an effective method to reduce the risk for HCMV infection and/or reactivation by restoring immunity in transplant recipients. However, the CMV-specific CD8(+) T cell response is comprised of a heterogenous mixture of subsets with distinct functions and localization, and it is not clear if current adoptive immunotherapy protocols can reconstitute the full spectrum of CD8(+) T cell immunity. The aim of this review is to briefly summarize …

A Microrna/Runx1/Runx2 Network Regulates Prostate Tumor Progression From Onset To Adenocarcinoma In Tramp Mice., Nicholas H Farina, Areg Zingiryan, Jacqueline A Akech, Cody J Callahan, Huimin Lu, Janet L Stein, Lucia R Languino, Gary S Stein, Jane B Lian

Department of Cancer Biology Faculty Papers

While decades of research have identified molecular pathways inducing and promoting stages of prostate cancer malignancy, studies addressing dynamic changes of cancer-related regulatory factors in a prostate tumor progression model are limited. Using the TRAMP mouse model of human prostate cancer, we address mechanisms of deregulation for the cancer-associated transcription factors, Runx1 and Runx2 by identifying microRNAs with reciprocal expression changes at six time points during 33 weeks of tumorigenesis. We molecularly define transition stages from PIN lesions to hyperplasia/neoplasia and progression to adenocarcinoma by temporal changes in expression of human prostate cancer markers, including the androgen receptor and tumor …

Unique Metabolic Features Of Pancreatic Cancer Stroma: Relevance To The Tumor Compartment, Prognosis, And Invasive Potential., Erik S. Knudsen, Uthra Balaji, Elizaveta Freinkman, Peter Mccue, Agnieszka K. Witkiewicz

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Pancreatic ductal adenocarcinoma (PDAC) has a dismal prognosis. The aggressiveness and therapeutic recalcitrance of this malignancy has been attributed to multiple factors including the influence of an active desmoplastic stroma. How the stromal microenvironment of PDAC contributes to the fatal nature of this disease is not well defined. In the analysis of clinical specimens, we observed diverse expression of the hypoxic marker carbonic anhydrase IX and the lactate transporter MCT4 in the stromal compartment. These stromal features were associated with the epithelial to mesenchymal phenotype in PDAC tumor cells, and with shorter patient survival. Cultured cancer-associated fibroblasts (CAFs) derived from …

Stimulation Of Transforming Growth Factor-Β1-Induced Endothelial-To-Mesenchymal Transition And Tissue Fibrosis By Endothelin-1 (Et-1): A Novel Profibrotic Effect Of Et-1., Peter J. Wermuth, Zhaodong Li, Fabian A. Mendoza, Sergio A. Jimenez

Department of Medicine Faculty Papers

TGF-β-induced endothelial-to-mesenchymal transition (EndoMT) is a newly recognized source of profibrotic activated myofibroblasts and has been suggested to play a role in the pathogenesis of various fibrotic processes. Endothelin-1 (ET-1) has been implicated in the development of tissue fibrosis but its participation in TGF-β-induced EndoMT has not been studied. Here we evaluated the role of ET-1 on TGF-β1-induced EndoMT in immunopurified CD31+/CD102+ murine lung microvascular endothelial cells. The expression levels of α-smooth muscle actin (α-SMA), of relevant profibrotic genes, and of various transcription factors involved in the EndoMT process were assessed employing quantitative RT-PCR, immunofluorescence histology and Western blot analysis. …

Recurrent Violent Injury: Magnitude, Risk Factors, And Opportunities For Intervention From A Statewide Analysis., Elinore Kaufman, Kristin L. Rising, Md, Ms, Douglas J. Wiebe, David J. Ebler, Marie L. Crandall, M. Kit Delgado

Department of Emergency Medicine Faculty Papers

INTRODUCTION: Although preventing recurrent violent injury is an important component of a public health approach to interpersonal violence and a common focus of violence intervention programs, the true incidence of recurrent violent injury is unknown. Prior studies have reported recurrence rates from 0.8% to 44%, and risk factors for recurrence are not well established.

METHODS: We used a statewide, all-payer database to perform a retrospective cohort study of emergency department visits for injury due to interpersonal violence in Florida, following up patients injured in 2010 for recurrence through 2012. We assessed risk factors for recurrence with multivariable logistic regression and …

Chemical Modification Of Extracellular Matrix By Cold Atmospheric Plasma-Generated Reactive Species Affects Chondrogenesis And Bone Formation., Peter Eisenhauer, Natalie Chernets, You Song, Danil Dobrynin, Nancy Pleshko, Marla J Steinbeck, Theresa A. Freeman

Department of Orthopaedic Surgery Faculty Papers

The goal of this study was to investigate whether cold plasma generated by dielectric barrier discharge (DBD) modifies extracellular matrices (ECM) to influence chondrogenesis and endochondral ossification. Replacement of cartilage by bone during endochondral ossification is essential in fetal skeletal development, bone growth and fracture healing. Regulation of this process by the ECM occurs through matrix remodelling, involving a variety of cell attachment molecules and growth factors, which influence cell morphology and protein expression. The commercially available ECM, Matrigel, was treated with microsecond or nanosecond pulsed (μsp or nsp, respectively) DBD frequencies conditions at the equivalent frequencies (1 kHz) or …
